H20DB-37-SS-500-ABZC Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Model H20® Incremental Encoder
Model H20® Incremental Encoder
The H20 is an extremely rugged encoder designed to economically
fill the resolution range up to 4096 cycles per turn. This compact
unit features a shock resistant disc, heavy duty bearings, and EMI
shielding. The H20 conforms to NEMA 4 and 13 requirements. The
H20 is also available in a hub shaft style with a flexmount (inset) for
easy mounting directly to small motors. Typical applications of the
H20 include machine control, process control, agricultural machin-
ery, textile equipment, robotics, food processing, and metering.
Special Models of the H20 Incremental Encoder are available with one or
more of the following certifications. Consult factory for details.
